SequelizeDatabaseError：Koa.js 框架中不存在關系“用戶”

Question

我有兩個模型 user 和 acessToken ，我正在嘗試建立這兩個表之間的關系，但出現錯誤。

模型如下：-

1. 用戶模型：-

 const { hashPassword } = require('../utils'); module.exports = (sequelize, DataTypes) => { const User = sequelize.define('user', { username: { type: DataTypes.STRING, allowNull: false, primaryKey: true }, email: { type: DataTypes.STRING, allowNull: false, validate: { isEmail: true } }, password: { type: DataTypes.STRING, allowNull: false }, role: { type: DataTypes.ENUM, values: ['admin', 'user'], allowNull: false, defaultValue: 'user' } }, { hooks: { beforeCreate: user => hashPassword(user).then(hash => { user.password = hash; // eslint-disable-line no-param-reassign }) } }); User.associate = models => { models.user.hasMany(models.accessToken); }; return User; };

2. 訪問令牌模型：-

 const crypto = require('crypto'); module.exports = (sequelize, DataTypes) => { const AccessToken = sequelize.define('accessToken', { username: { type: DataTypes.STRING, allowNull: true }, token: { type: DataTypes.STRING, allowNull: false, defaultValue: function defaultValue() { return crypto .randomBytes(48) .toString('base64') .replace(/\\//g, '_') .replace(/\\+/g, '-'); } } }); AccessToken.associate = models => { console.log('models =>', models); models.accessToken.belongsTo(models.user); }; return AccessToken; };

我正在嘗試在這兩個模型中插入數據，如下所示：-

 try { userData = await models.user.create({ username, email, password }); } catch (e) { return ctx.throw(500, `creating user failed! :( ${e}`, e); } try { tokenData = await models.accessToken.create({ username }); } catch (e) { return ctx.throw(500, `creating accessToken failed! :( ${e}`); }

所以我收到以下錯誤：-

Executing (default): INSERT INTO "users" ("username","email","password","role","createdAt","updatedAt") VALUES ($1,$2,$3,$4,$5,$6) RETURNING *;

誰能告訴我哪里做錯了我無法識別錯誤。

Answer 1

嘗試在用戶模型中有鈎子的地方添加它...

freezeTableName: true,
tableName: 'user',
